In addition to InMotion, and Let there also is dyno-comp which uses renntech tunes, powerchip, kleeman, and evosport.

I'm biased with my InMotion tune. I have the smallest crank pulley 178, but currently the 2nd fastest SRT6 around. Now to be fair my tune was specifically created for my Needswings parts combo. For being a version one of this tune, it sure is a good one. I suggest that you get some feedback on the C32 section of MBworld. There may be an affiliated tuner in Germany that would make it more convenient. I'd even try Korea or Japan for additional options. It's going to be expensive any way you look at it.
